Title: Recording method for magneto-optical recording and reproducing device
Inventor: KUWATA NAOKI
IPC: G11B5/02
Filed: 1987-05-01
Abstract: PURPOSE:To enable overwrite to be performed without necessitating an erasing operation, by writing data by inverting the direction of an external impressing magnetic field corresponding to the number of times of the overwrite at a flag part provided in a sector. CONSTITUTION:When information is recorded at the initializing state 22 of a magneto-optical recording medium, the output waveform 23 of a laser is projected, and also, an external magnetic field is impressed in a direction of arrow head. Thereby, the information is recorded as a state 24, and a reproducing waveform 25 can be obtained. When the overwrite is performed on the waveform, by projecting the output waveform 26 of the laser and also, inverting the external impressing magnetic field, the state 24 is completely erased, and the magnetized pattern of a state 27 is recorded. Therefore, the number of times of the overwrite is read from a flag provided in the sector by a preceding beam at every write and reproduction, and by performing the switching of the external impressing magnetic field and the delay of a recording data pulse corresponding to the odd and even of the number of times, it is possible to perform the overwrite without necessitating the erasing operation.

Title: Focus detecting device
Inventor: ISHIDA TOKUJI
IPC: G02B7/28
Filed: 1989-04-26
Abstract: PURPOSE:To obtain the focus detecting device which performs stable and suitable focus detection without reference to photographic magnification by switching methods for calculating the quantity of defocusing of a focus detection area from the quantities of defocusing of respective blocks according to the photographic magnification. CONSTITUTION:A defocusing quantity determining means 4 determines the quantity of defocusing of a photographic lens from the displacement detection signal outputted by a focus detecting means 3. Further, the calculated photographic magnification is compared with a specific magnification value and when the photographic magnification exceeds a specific magnification value, the quantities of defocusing of the respective blocks are averaged to calculate the quantity of defocusing of a focus detection area from the averaged value. When the photographic magnification is smaller than the specific magnification value, the quantity of defocusing of one block among the quantities of defocusing of the respective block is calculated and the quantity of defocusing of the focus detection area is calculated from the quantity of defocusing. Consequently, the suitable focus detection is stably performed for a main object in a photographic image plane.
